Specification 411,767 is referred to.
Patent GB-918380-A (GB)
Title: Improvements in and relating to arene metal carbonyls
IPC: C07F17/00
Filed: 1960-10-17
Abstract: The invention comprises bis(arene-metal) carbonyls of formula <FORM:0918380/IV (b)/1> where M is manganese or rhenium, each R represents hydrogen or an alkyl group and only one arene group is bonded to each metal atom. The arene compound may be benzene, toluene, o-xylene or mesitylene.  Typical compounds are bis(benzene manganese)tetracarbonyl, bis (o - xylene manganese) tetracarbonyl, bis(toluene rhenium)tetracarbonyl and bis(mesitylene manganese)tetracarbonyl.  The compounds of the invention may be prepared by reacting a manganese or rhenium carbonyl with an arene organic compound in an inert liquid organic solvent at a temperature between 0 DEG  and 300 DEG C.  The inert solvent may be heptane, petroleum ether or an aromatic compound which does not react under the particular reaction conditions.  A basic catalyst such as a substituted pyridine (2-methylpyridine, 2,6-dimethylpyridine, 2,4,6-trimethylpyridine) or a tertiary amine (N,N-dimethylaniline, tributylamine, triethylamine) may be added to the reaction mixture. Stoichiometric proportions may be used, but it is preferred to use the aromatic compound in excess.

Abstract: 1,014,178. Coating wire. C. F. BETTNER. Sept. 18, 1962, No. 35439/62. Heading D1L. A die for determining the thickness of a coating applied to a wire comprises two side walls, an additional portion extending inwardly from each side wall, a bushing having a passage way therethrough, the bushing being carried by the additional portions and divided in a plane intersecting the passageway, and locking means for preventing relative movement between the divided parts of the bushing in a direction parallel to the dividing plane, the divisions of the bushing being biased together. In the embodiment shown a bushing holder 10 having side walls 11 and 12 with inwardly extending top portions 13 and 14 supports two halves 18,19 of bushing 20. Also extending from walls 11, 12 are two intermediate portions 21, 22 the former having a recess 23, 24 which receives a projection extending from the portion 22 so as to prevent any movement between the two halves 18, 19 of bushing 20 in the direction of the plane dividing them. A bottom portion 28 having a slot 29 therein is so formed as to spring urge the two halves of bushing 20 into contact with each other.

Title: Coaxial magnetron
Inventor: POWELL KENNETH DEAN
IPC: H01J25/55
Filed: 1966-08-10
Abstract: 1,134,734. Magnetrons. WESTINGHOUSE ELECTRIC CORP. 10 Aug., 1966, No. 35753/66. Heading H1D. In a coaxial magnetron having an outer cavity 32 coupled by slots with alternate cavities formed by the anode vanes 38 (Fig. 2, not shown), and with upper and lower polepieces 22 and 34, the envelope is assembled by welding together the flanges 16, 46, and 82, formed at the lower ends of the outer resonator wall 14, the anode cylinder 36, and the collar 80, respectively, whereby brazed joints are avoided. The outer resonator is designed to oscillate in the TE 011  mode, the undesired TE 121  mode being coupled out and attenuated via a small annular gap 90 between the wall 14 and the anode cylinder 36, which gap gives access to a groove 51 in the wall 14 housing a carbon-loaded attenuator ring 52 which is spring-loaded by member 50 against a matching ceramic ring 54. The ceramic output window 106 is mounted in a circular waveguide section 102 sandwiched between two rectangular waveguide sections 100 and 104, wires 108 welded along the longer sides of the latter (Figs. 3 and 4, not shown) at their junction with the circular section providing, by suitable choice of the wire diameter, capacitive irises which permit matching of the output together with the use of the optimum thickness of window 106. The upper polepiece 22 includes an exhaust passage, and the manner of mounting the cathode 24 within the lower polepiece 34 permits the use of an emissive surface 64 having a diameter greater than the internal diameter of the polepieces.

Title: Speed control of line followers
Inventor: TRAPP GEORGE JOSEPH
IPC: B23K7/00
Filed: 1969-07-16
Abstract: 1,273,632. Programmed electric control. G. J. TRAPP. July 16, 1969, No.35784/69. Heading G3N. A number of outlines 136, 137 are followed by separate (photo-electric) line followers 130, 132 to guide separate tools, e.g. flame cutters 131, 133, the drive in one direction being at a common speed which is determined by comparing "desired speed" signals from each of the followers and selecting that which represents the slowest in the said direction. Each follower has a magslip or potentiometric resolver whose X and Y outputs depend upon the direction of the line immediately beneath it and attempt to control speed of movement in these directions so as to keep cutting speed (i.e. the resolute) constant. However, the followers and cutters are mounted on a common main carriage for longitudinal (Y, or downwards as shown) movement, driven by a motor whose speed is controlled by a magnetic amplifier having a control winding energized by a transistor circuit. In Fig. 3 (not shown) this circuit applies the Y output of each resolver, via transistors, to a network of diodes, all of which are reverse biased except that associated with the lowest input, which is thus effective to control the common Y motor. An alternative circuit Fig. 4 (not shown) is similar, except that X input signals are used and the circuit responds to the highest (which corresponds to lowest Y). The arrangement shown includes a modification which provides brief reverse travel in the Y direction, to follow reentrant portions 142, 145. For this, one or more of the followers and cutters are mounted on sub carriages 128, 129; the control circuit Fig. 7 (not shown) has a phase sensitive network which detects a requirement for back travel and this stops, or preferably decreases to a minimum, the travel of the main carriage while controlling a separate motor which produces the required back travel. This circuit also has a diode network similar to that of Fig. 3

In a combined ophthalmoscope and camera the retina is illuminated by an annulus of light from the source S via stop Y, lens L R , and semitransparent mirror F 3 . The image of the cornea obtained by reflection is focused by the lenses L 1 , L 2  on the stop D and thus prevented from reaching the film E, by having the cornea B at the front focal plane of the lens L 1  and the stop D in the rear focal plane of the lens L 2 . The lens L 2  and stop D are movable in combination so that the image of the retina formed by lens L 1  and the eye is in the front focal plane of lens L 2  and thus focused on the camera film E which is in the rear focal plane of the lens L 3 .
